Despite it being a really short demo, I enjoyed where it was headed. The story and premise are interesting, and the phone's features and re-hashing of RPGMaker's default saving/loading system were pretty cool. It helped make everything feel a little more immersive, even if there isn't much here.
I do wish the controls for Keyboard & Mouse were more intuitive, as they do feel kind of janky and uncomfortable to play with.
The designs for Ayaka and Mitsuki should be way more visually distinct from one another, as one looks like a carbon copy of the other. It'll help distinguish them and their personalities better, I feel.
Regardless, this was solid. I enjoyed Rainbound for what it was.
